Particulate measurement downstream of the filter for detecting faulty filter bags and for fire detection

For vacuum degasser installations operated with mechanical pumps, dust must be removed before entering the pumps. Otherwise, damage occurs resulting in repair cost for the pumps and production loss. Therefore, the gas is cleaned by a filter equipped with filter bags. If the filter medium is damaged, a dust monitor detects an increase in particulate matter, enabling countermeasures to be implemented in order to protect the pumps. A DUSTHUNTER dust monitor can also be used to detect a fire in the filter house, since combustion products such as smoke also increase particulate matter levels.
